Introduction to Cisco_FTD_SSP_Patch-7.4.1.1-12.sh.REL.tar
This urgent security patch addresses critical vulnerabilities in Cisco Firepower Threat Defense (FTD) software version 7.4.1.1 for Firepower 4100 Series and 9300 Series appliances with Security Services Processor (SSP) modules. Released under Cisco’s accelerated security response program, the update specifically mitigates path traversal risks in WebVPN services and memory corruption flaws in SSL/TLS session handling.
The “7.4.1.1-12” designation indicates this is the 12th cumulative patch for FTD 7.4.1.1 base code, incorporating fixes from 11 previous iterations. Cisco’s Quality Assurance team confirms backward compatibility with threat policies created in FTD 7.2.x through 7.4.2 environments.
